P
PAEONIA
Paeony, Molly the Witch. A very choice clump-forming perennial produces single bowl-shaped, pale lemon-yellow flowers, in early summer. Two year old plants which will take about three years to reach flowering size, but worth the wait!
papaver
ORIENTALE VARIETIES A must for the herbaceous border. Make sure you decide where you want it, before you plant–it propagates by root cuttings. Each individual flower is not very long lasting but they are very showy and produce a succession during the early summer. They do like a sunny situation and even do well in our heavy clay soil. After flowering the plant goes dormant so we inter-plant with annual Cosmos which seems to be very effective.
Large blood red flowers, with dark central blotches to the petals, in midsummer. Sells on sight, as very upstanding, a 'sock it in the eye' type of flower.
Pale pink flowers with black central blotches.
Plum coloured poppy, with dark centre, in midsummer.
Large shocking pink flowers, with thick black markings in the centre. A very striking oriental poppy, not easily missed!
Semi double pale pink and almost white frilly flowers.
parahebe
Glossy green leaves with white flowers and a deep pink eye. Forms a small evergreen mound.
PASITHEA
Say the name to yourself and it sounds as if you have developed a lisp. A good drought tolerant plant with loose spikes of good blue flowers from May to August. Hardy.
pennisetum
Brown hairy caterpillar flowers in early autumn.
Forms green tussocks of foliage, with dark reddish-brown fluffy flowers, like hairy caterpillars from mid to late summer.
penstemon
The larger Penstemons can be treated like a hardy fuchsia and cut to 15 cm above the ground in April (they will then provide a long display of flowers from mid to late summer). As a general guide, the narrower leaved Penstemons are the hardiest. The smaller ones just need a light trim in the autumn after flowering to help keep their shape, and very well-drained soil.
A rosette of glossy green foliage, sends up spikes of scarlet-orange tubular flowers from midsummer. Great for the flame border.
Small, pretty tubular-shaped, rose-pink flowers with paler pink insides, for weeks in summer. Hardy
Largish pinky crimson tubular flowers, with white in the throat, for months from July. Very hardy.

Pink tubular flowers for months in summer and early autumn. Seems pretty hardy.

A dwarf shrub of pinnate leaves with tubular orangey-red flowers from early summer onwards. Very hardy.
Lemon-yellow flowered form of the above.
Tubular maroon flowers, with paler insides, for weeks, from midsummer. Hardy in most gardens, but seems more susceptible to eelworm than some.

perovskia
Grey felty leaves grow up the white coated stems. Many branching terminal spikes of blue flowers that sort of glisten as they are coated in fine hairs, in late summer. Likes well-drained soil.
persicaria
A mat-forming, evergreen perennial with dark green leaves turning brown in autumn and spikes of pale pink flowers becoming deep pinkish red, from July to October.
A clump forming perennial with glowing orange-red bottlebrush flowers for weeks from July.
phlox
Most of the phlox we grow apart from are good for the rockery. They form low, often trailing mounds of needle-like leaves, covered in flowers in early spring. They do not seem to thrive in too dry a situation and the Phlox bifida types do well in partial shade. If cut back slightly after flowering it keeps them from getting too woody.
Very tight mound of needle-like foliage, with palest lilac flowers in spring. Likes fairly well-drained soil.

picea
A neat cone-shaped dwarf evergreen conifer with bright green needle-like leaves. Very slow growing, ours is still only 1.6 m high after fifteen years. Suitable for the larger rockery.
pimpinella
Very similar to a pink flowered cow parsley, but with slightly less divided leaves. Dusky pink flowers on upright stems in May and June.
polemonium
Upright Jacob’s Ladder with creamy variegated foliage and small violet blue flowers in April-May. It benefits from fairly rich, moist soil. (PBR)
Sprawling stems of lilac-mauve flowers on and off throughout summer. Not too dry a situation.

pterocephalus
Pale green felty foliage with round heads of pretty pink scabious-like flowers in summer. Makes a large carpet.
pulmonaria
Otherwise known as ‘Lungwort’. They like a moist soil in sun or shade. After flowering, they can be cut right back to promote fresh new leaves, which provide useful groundcover. They flower in late winter to early spring, providing valuable early nectar for bees.
