Garden & Ecology Notes

Wildlife Value:
birds, small mammals, beavers
Fragrant:
Yes
Fall Color:
yellow
Fire Ecology:
Fire adapted — tolerates or benefits from fire
Fire Notes:
Resprouts vigorously from roots and stumps following fire. Young trees are fire-sensitive but mature trees can survive low-intensity fires.

Soil Requirements

Soil Type:
fertile, moisture-retentive loam
pH:
5.5 - 8.0 (slightly acidic to neutral)
Drainage:
tolerates poor drainage
Moisture:
consistently moist
Notes:
Commonly found in floodplains and riverbanks.

Propagation & Germination

Stratification:
None required
Germination Time:
1–7 days
Notes:
Seeds are short-lived and must be sown immediately after collection on moist soil. Light required for germination.

The above propagation data sourced from Claude AI

Pre-treatment: For seeds, germinate at 32 C. For cuttings, stick to a depth of 10 cm in a 2:1:1 (v:v:v) peat:perlite:vermiculite mixture. Controlled release fertilizer 14-14-14 (N-P-K) 3 -4 month is incorporated into the media at the rate of 4 kg/m3. Cuttings are watered in and kept moist throughout the rooting period using an intermittent misting schedule.

Establishment: For seeds, the germination medium used is a standard sphagnum peat moss and perlite mix of fairly coarse texture (Sunshine #1). For cuttings, stem cuttings are taken from dormant trees growing in stooling blocks in February (or anytime from January to late March). The earlier the cuttings are taken (January thorough February) the longer the cuttings can be stored before bud burst occurs during storage.
