Shrubs Honor - advanced

Nature Study

Requirements

  1. Have the Shrubs honor

    Answer: You need to have completed the Shrubs honor (regular) before starting the Advanced one. The regular one covers the fundamentals: definition of a shrub (vs. tree and herbaceous plant), basic morphology (short woody stem, several branches), common examples, basic care (pruning, watering, fertilizing). — Shrubs are woody plants up to ~5m tall with several branches from the base — different from trees (1 main trunk) and herbaceous plants (non-woody stem). The regular honor provides the technical botanical vocabulary without which the advanced one becomes confusing and lacks a solid foundation.

  2. Know what ornamental shrubs are and discover at least one technique for ornamenting shrubs.

    Answer: Ornamental shrubs are grown for their beauty (foliage, flowers, shape), not for their usefulness. E.g.: azalea, hibiscus, boxwood. Techniques: TOPIARY (geometric/animal shapes), BONSAI (miniature), CONE/BALL PRUNING, ESPALIER (against a wall). — Topiary has existed since Ancient Rome (1st century) — the palace of Versailles has famous examples. Bonsai comes from Japan (6th century) and requires decades of care. Espalier is a European technique of training a shrub against a wall or trellis to save space in small urban gardens.

  3. Care for a shrub for at least 1 month and report your care methods.

    Answer: For 1 month, care for a shrub recording: watering (frequency according to the species), fertilizing (organic or NPK as needed), pruning of dry leaves/branches, pest control (aphids, scale insects), weekly inspection. Report with before/after photos and observations of growth or any problems observed. — Shrubs require regular but not very intensive care. Overwatering is the #1 mistake (it rots the root). NPK 10-10-10 fertilizer works for most. Weekly visual inspection detects pests early (easier to treat). A care diary is a professional horticultural practice used by serious gardeners.

  4. Give 3 examples of the following types of shrubs:
    • Flowering shrubs
    • Fruiting shrubs

    Answer: 1) Flowering shrubs (3 examples): azalea (Rhododendron simsii, with pink, white, or red flowers), hibiscus (Hibiscus rosa-sinensis, with large flowers in varied colors), and camellia (Camellia japonica, with long-lasting flowers). 2) Fruiting shrubs (3 examples): Surinam cherry (Eugenia uniflora, which produces the pitanga), dwarf guava (Psidium guajava in reduced size), and mulberry (Morus nigra, with wild fruits). — Flowering ones prioritize aesthetics (colors, flower shape); fruiting ones produce food. The Surinam cherry is native to Brazil and fruits in summer. Hibiscus blooms all year in a tropical climate. The camellia was a symbol of European nobility in the 19th century. The dwarf guava (~2m) fits in a pot on an urban balcony.

  5. Observe a shrub that is in bloom and list as many insects as possible (at least 3) that come to seek pollen or nectar in its flowers.

    Answer: Observe a blooming shrub (morning/afternoon) and identify 3+ insects: BEE (seeks pollen), BUTTERFLY (nectar with proboscis), MOTH (nocturnal), BEETLE (large flowers), CARPENTER BEE (buzzes loudly). Note the name, frequency, and preferred flower of each one. — Pollination is an essential process — without insects, 80% of flowering plants do not reproduce (IPBES study, 2016). Brazilian Africanized bees pollinate ~70% of commercial crops. Observing visitors trains ecological awareness and prepares you for broader discussions about the environment and sustainability.

  6. Name 3 important wild or cultivated foods found on shrubs in your area.

    Answer: 3 common foods on shrubs in Brazil: SURINAM CHERRY (Eugenia uniflora, native, high in vitamin C), MULBERRY (Morus nigra, antioxidant), GUAVA (Psidium guajava, source of vitamin C). Other regional ones: araçá, cambuci, jabuticaba (on a shrub/small tree). Identify and name 3 from YOUR region. — The Surinam cherry is a symbol of native Brazilian fruit, with 3-4x more vitamin C than an orange. Guava was domesticated by Brazilian indigenous peoples before the Portuguese arrival. Mulberry grows wild throughout Brazil. Wild fruits generally have more antioxidants than industrially cultivated ones.

  7. List at least 60 different types of shrubs and collect, preserve, and correctly identify the flowers, leaves, seeds, seed pods, or budding twigs of at least 20 of the shrubs listed.

    Answer: An exsiccata is the universal method of scientific herbaria — used by professional botanists for 400 years. Pressing between newspaper absorbs moisture. A label with scientific name, common name, location, and date is the standard for any herbarium. 60 species is a significant task that requires several weeks of dedicated work.
