The Artwork of APPS 2025
Explore Margaret Senior's 1964 plant pathology illustrations chosen as the APPS 2025 artwork, and what they reveal about the early science in Sydney.

You look at a botanical illustration and you ask a simple question. What lets you trust what you see? Leaf shape, bark texture, flower detail and growth habit all need a living plant you can check, a preserved specimen you can compare, and a name you can rely on. That is where a scientific garden helps you. It keeps plants with known wild origins beside herbarium sheets, keeps records of where each plant grows, and keeps names aligned with current taxonomy.
The details cited in this entry were checked on living collection pages.
The Gardens' living collection page does not publish notes on illustration technique.
What does accurate plant art need behind it?
When you study art made to explain disease or plant form, you need more than a pretty image. You need to know which species was drawn, where that plant came from, and whether the name on the label still stands. A garden that documents provenance gives you that chain. You can move from a planting you walk past to a record that tells you its identity, then to a herbarium sheet that preserves diagnostic characters for study. That chain is what turns observation into plant pathology, biosecurity work, or teaching that you can defend.
How large is the living collection you can check?
Scale matters when you try to learn native flora. The page reports around 77,000 individual plants and over 4,600 species. Those plants grow across themed plantings and in the nursery and glasshouse areas set aside for care and propagation. For you, that means you are not looking at a small display bed. You are looking at a broad sample that lets you compare close relatives side by side, see variation within a species, and notice when symptoms or morphology depart from the usual pattern in a planting.
Why does one fifth matter to you?
The page states that the species held represent around a fifth of Australia's native plants. Consider what that coverage gives you as a student, grower, or extension officer. If you work with crops near native vegetation, you often meet hosts, alternate hosts, or lookalike species outside the paddock. A collection that holds a substantial share of the flora lets you check leaf, fruit, and habit characters in person rather than guessing from a photo. You build a visual memory that helps you describe what you see in the field with precision.
Where do you find a plant across 40 hectares?
Forty hectares of themed sections can feel large when you arrive with a name on a slip of paper. The page points you to tools that narrow the search, including a living plant finder and a finder for sections and their plants. You can look up living collection pages to orient your walk before you set out, then use section-level plantings to compare members of one group in one place. Themes shape those plantings, so you see ecological and geographic associations instead of isolated specimens. That layout helps you ask why a species grows where it does and what conditions keep it healthy.
Why do wild origins change the science?
Many amenity plantings come from horticultural selections with complex histories. The page describes a different approach. Plants here originate from wild populations and are accompanied by herbarium specimens kept for taxonomic study. For you, wild origin means the characters you observe relate back to natural populations rather than to a selected clone. When researchers work with these plants, or with specimens held at the Australian National Herbarium, they can rely on documented provenance and on classification and naming kept current. You get identification you can cite and comparisons you can repeat.
How do living plants and herbarium sheets work together?
You learn most when you use both forms of evidence. A living plant shows color, texture, phenology, and response to season and water. A herbarium sheet fixes diagnostic details in time and preserves them for measurement under magnification. The page links these two sides through the Plant Records Unit and through ties to the Australian National Herbarium. If you want to sharpen your taxonomy skills, study how a living crown matches its pressed counterpart and read current naming carefully. The herbarium and taxonomy guide shows you how to handle that comparison without reading too much into a single specimen.
What do nursery, glasshouses and seed bank hold for you?
Behind the public plantings you find working areas that keep the collection alive and usable. The page lists a nursery, glasshouses, horticulture operations, landscaping care, water-wise practice, and a seed bank. Each has a role you can understand in plain terms. The nursery raises young plants for display and replacement. Glasshouses shelter plants that need controlled warmth or humidity. The seed bank stores seed for future propagation and study. Horticulture and landscaping keep plantings true to their themes while managing water with care. When you see a thriving bed, you are seeing that back-of-house work expressed above ground.
How do records, themes and horticulture help you read a planting?
Themed sections do more than please the eye. They group plants so you can learn relationships and habitat preferences as you walk. Records support that walk. The Plant Records Unit tracks identity and location, while section finders help you plan which beds to visit and what to look for. The page also lists horticultural information, a library, and field trip information that extends learning beyond a single visit. If you join structured walks or review field trip notes afterward, you can connect what you saw outdoors with names and characters you test again at your desk.
What should you check before you use or take a plant?
Scientific value depends on control. You cannot clip, collect, or propagate at will in a taxonomic collection, and you should not assume that every plant is available for sampling. The page lists permits for removing plants and points to records and staff expertise for legitimate inquiry. Use the finder to confirm identity and location, note the section and the record details, write down the current name exactly as shown, and contact the relevant unit with a clear request that states purpose and quantity. That discipline protects provenance, keeps names stable for the next user, and preserves the link between living plants and herbarium vouchers.
Plan your next visit around one genus you keep confusing in the field. Look up its section, walk the beds, photograph the habit and close characters with a scale, then compare your notes with herbarium practice and the seed-bank and nursery roles described on the page.
