Phenological Markers

1. New Vegetative Growth

Look for:

• Fresh growth at branch tips
• Pale green young stems
• Small, soft new leaves
• Leaves appearing in opposite pairs
• Rapid extension of new shoots

As leaves mature, they become darker green, firmer, and more leathery.

2. Mature Foliage

Look for:

• Dense evergreen foliage
• Small, leathery leaves
• Opposite leaf arrangement
• Little visible shoot extension
• Mature stems becoming woody

Because the plant is evergreen, a completely leafless dormant period would be unusual under normal conditions.

3. Flower Cluster Formation

Flowers arise in small clusters, usually from the leaf axils.

Look for:

• Tiny swellings where leaves join the stem
• Short branching flower stalks
• Groups of minute flower buds
• Several developing clusters along a branch

The flowers are very small and may be difficult to notice without close inspection.

4. Flower Buds

Look for:

• Minute rounded buds
• Green to reddish or purplish coloration
• Individual buds separating within the cluster
• Several stages of bud development present simultaneously

Macro photography is particularly useful at this stage.

5. Open Flowers

Look for:

• Very small open flowers
• Four petals
• Greenish flowers often showing reddish tones
• Several flowers opening within the same cluster
• Unopened buds remaining nearby

The flowers are subtle and easily overlooked, so flowering may be underway before it is obvious from a distance.

6. Pollinator Activity

Look for:

• Small flies
• Tiny bees or wasps
• Other minute insects moving among the flowers
• Repeated visits to several flower clusters

Record the time of day and weather conditions whenever possible.

7. Flower Senescence

Look for:

• Petals drying or disappearing
• Flowers collapsing
• Empty flower stalks
• A small green swelling remaining after successful pollination

Unpollinated flowers may simply fall away.

8. Initial Fruit Set

Look for:

• Tiny green fruits appearing where flowers had been
• Fruit beginning to enlarge
• Several young fruits developing together
• Persistent floral structures sometimes remaining at the fruit tip

This is an important transition to photograph.

9. Green Fruit Development

Look for:

• Small smooth green fruits
• Fruit becoming more rounded or slightly elongated
• Increasing fruit size
• Fruit clusters becoming easier to see against the foliage

10. Colour Break

One of the easiest phenological stages to recognize.

Look for:

• Green fruit beginning to turn yellowish, orange, or red
• Uneven colour development
• Green and red fruits occurring together
• Increasing contrast between fruit and foliage

Photographing the same cluster repeatedly can provide an excellent ripening sequence.

11. Mature Fruit

Look for:

• Bright scarlet-red fruit
• Smooth fruit surface
• Several mature fruits clustered together
• Mixture of ripe and unripe fruits on the same branch

The bright red fruit is much more conspicuous than the flowers and is one of the plant’s easiest field markers.

12. Fruit Removal and Dispersal

Look for:

• Ripe fruits disappearing from previously photographed clusters
• Empty fruit stalks
• Birds visiting the plant
• Damaged or partially eaten fruit
• Fallen fruit beneath the canopy
• Seeds or fruit remains nearby

Bird observations may be especially valuable because the bright fruit strongly suggests animal-assisted dispersal.

13. Seedling Emergence

Look for:

• Small seedlings beneath or near the parent plant
• Newly emerging paired leaves
• Young plants appearing in areas where fruit has fallen or been carried

14. Leaf Ageing and Replacement

Look for:

• Older leaves becoming pale green or yellow
• Occasional brown margins
• Individual leaves dropping
• New growth appearing while older leaves are shed

Leaf replacement may occur gradually rather than as a distinct seasonal event.

Suggested Observation Schedule

Observe the plant monthly, increasing to weekly or biweekly when flowering or fruiting is active.

Record:

• Date
• Rainfall since previous observation
• New shoot growth
• New leaves
• Flower buds
• Open flowers
• Pollinator activity
• Initial fruit set
• Green fruits
• Colour-changing fruits
• Scarlet mature fruits
• Fruit disappearance
• Bird activity
• Leaf yellowing or shedding
• New seedlings

Suggested Abundance Scale

0 — Absent
1 — Very few
2 — Occasional
3 — Common
4 — Abundant
5 — Peak activity

Phenological Sequence

New shoot growth → flower cluster formation → flower buds → open flowers → initial fruit set → green fruit → colour break → scarlet fruit → fruit dispersal

Several stages may occur at the same time.

Best Photographic Sequence

For this species, I would try to capture:

Flower bud → open flower → newly set green fruit → enlarging green fruit → partially red fruit → mature scarlet fruit

Because the flowers are so small, the transition from flower to fruit may ultimately be the most scientifically useful part of the Garden record.

Particularly Valuable Garden Observations

Three questions would be especially useful to answer locally:

Does flowering increase after rainfall?

How long does it take a newly formed green fruit to become scarlet?

Which birds or other animals remove the mature fruit?

Over several years, those observations could give the Garden a genuinely local phenological record rather than relying only on observations made elsewhere in the species’ range.
