|Perlargonium quercifolium 'Royal Oak'|
The oak leaf shaped leaves give this species plant the name 'quercifolium' as in quercus sp. It is also known and sold as Royal Oak. A large and shrubby plant, I like to grow this in a planter which is moved outside fairly early on in the summer as it seems to be fairly tolerant of cooler weather, and I bring it inside later than other pelargoniums. It does like sunshine and likes to be kept on the dry side. It has fairly large and very beautifully marked flowers over a very long season - my plant is still flowering in the greenhouse now. The leaves have a dark blotch in the centre and feel sticky to touch. Although this is often sold as a scented plant, it is not a sweet scent, but rather is strong, like balsam.
P. quercifolium is found growing naturally in Cape Province on rocky slopes. The plant was introduced to Kew Gardens in 1774 by F. Masson.
