Quick Reference
- 'Dorothy Gordon' is one of the larger cultivars here (3m × 2m), with year-round mauve-pink blooms and better humidity tolerance than most compact varieties.
- Most Grevillea cultivars share the same core needs: full sun, free-draining low-phosphorus soil, and drought tolerance once established.
- For small gardens or pots, filter by "Compact" habit below — several varieties top out under 1m.
- Frost sensitivity varies more than most guides mention — check the Frost Tolerance column before planting in a cold-winter climate.

Troubleshooting & FAQ
How does 'Dorothy Gordon' compare to 'Robyn Gordon'?
'Dorothy Gordon' grows larger (about 3m tall vs. a smaller, compact habit for 'Robyn Gordon'), blooms year-round rather than seasonally, and tolerates humidity better. 'Robyn Gordon' is more frost-sensitive. Use the table above and filter by name to compare both directly.
Which Grevillea varieties suit small gardens or pots?
Filter the Habit column to "Compact" or "Prostrate." These cultivars generally stay under 1–1.5m and are better suited to containers or small borders than upright, screening-type varieties like 'Dorothy Gordon.'
Why are my Grevillea's leaves turning yellow?
Across nearly all cultivars in this table, yellowing leaves point to poor drainage or overwatering. Improve soil structure and reduce watering frequency before considering nutrient deficiency.
Do all Grevilleas need low-phosphorus fertilizer?
Yes. As Australian natives, every cultivar listed here is sensitive to high-phosphorus fertilizers, which can cause toxicity. Use a native-specific, low-phosphorus blend sparingly, if at all.
Which varieties tolerate frost best?
Sort the table by the Frost Tolerance column. Varieties marked "Light frost (established)" or "Moderate" generally handle occasional cold snaps once mature; young plants of any cultivar should be mulched and protected in their first winter.
