Plant description
A cross between hollyhock (Alcea spp.) and an Althaea, this tall plant puts on a prolific display of flowers, that no longer suffers rust like its forebear. ‘Parkallee’ forms a spreading vase shape, and its stems will be evenly studded with open bowl-shaped flowers from July to November. Each flower emerges a light apricot and fades to a buttermilk-cream as it matures. The centre of each is speckled with bronze stamens and a central frill of tiny petals.

How to care for Alcalthaea suffrutescens Parkallee:
Plant in full sun to light shade, in well-drained, humus-rich soil. Amend heavy or clay soils with compost prior to planting. Space plants 60-90cm (2-3ft) apart to allow for their upright, bushy habit. Provide sturdy support as the tall stems may require staking.
Apply a thick organic mulch around the base to retain moisture and suppress weeds. Deadhead spent flowers regularly to encourage extended blooming.
In cold winter regions, apply a layer of protective mulch around the crown. Cut old stems back when new basal growth is seen in spring.

Please note:
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
