Phenological Markers — Guavaberry (Myrciaria floribunda)
Family
Myrtaceae
Growth habit
Evergreen shrub or small tree with a dense crown and fine branching.
Leaf flush
New growth appears as soft, lighter green leaves at branch tips; young leaves may show a slight bronze or reddish tint before maturing.
Mature foliage
Leaves fully expanded, firm, and glossy to matte green; canopy appears dense and settled.
Flower buds
Tiny rounded buds form singly or in small clusters in the leaf axils along young branchlets.
Open flowers
Small white flowers open with many conspicuous stamens, giving a delicate brush-like appearance typical of Myrtaceae.
Peak flowering
Canopy lightly dotted with small white blossoms; effect may be subtle rather than showy, but close inspection reveals many open flowers.
Post-flowering / spent flowers
Petals and stamens fall quickly; the flower base begins to swell as tiny immature fruits develop.
Immature fruit
Small green berries visible along the twigs and in the leaf axils; fruit gradually enlarges while remaining firm.
Maturing fruit
Berries change from green through red or reddish-purple tones as they ripen, depending on stage and light exposure.
Ripe fruit
Fruit fully colored, typically deep red to dark purplish, softening slightly when mature.
Seed stage
Seeds fully developed within ripe berries; fruit may be taken quickly by birds and other wildlife.
Fruit drop
Ripe or overripe berries fall beneath the plant, sometimes attracting insects or birds; fallen fruit can be a useful cue when canopy fruit is hard to see.
Leaf fall
Generally light and continuous rather than strongly seasonal; occasional heavier leaf drop may occur during stress or drought.
Field cues for photography
- Leaf flush: look for paler or bronze-tinted new leaves at the ends of twigs.
- Flowering: easiest seen at close range because the white flowers are small.
- Early fruiting: tiny green berries after petals fall.
- Ripening: watch for berries shifting from green to red/purple.
- Ripe stage: darker colored berries, often with wildlife interest.
Simple scoring categories
You could record it this way on each visit:
- Leaf flush: none / light / moderate / heavy
- Flower buds: absent / present
- Open flowers: absent / few / moderate / peak
- Immature fruit: absent / few / moderate / many
- Maturing-ripe fruit: absent / few / moderate / many
- Fruit drop: none / light / heavy
- Leaf fall: none / light / moderate / heavy
