Delavay Privet Multi-Stem Balls Topiary Pair - Cumulo & Alto

Three of each. Every plant in your pair rises from its pot on three separate stems, and each stem carries exactly one clipped ball — a tall head, a middle one and a low one — so you see three spheres at three distinct heights, with bare stem showing beneath each. The stems leave the pot from their own points and splay slightly apart, which is what keeps the heads clear of one another. Ball sizes vary naturally from stem to stem; that variation is part of the form, and it is matched across the pair rather than ironed out. It is also what separates a multi-stem plant from our pom poms, where three to seven spheres sit on one branching framework.

No — and they shouldn't be. Multi-stem plants are naturally individual: no two grow their stems at exactly the same angle. What we match by hand is height, stem count, ball placement and colour, so the two plants share one rhythm — heads that sit level, stems that lean the same way — and read as companions rather than copies. Height is guaranteed to within 10cm, and before dispatch your quality-control certificate shows you six photographs of your actual two plants. If the pair that arrives isn't matched, email hello@topiarytwins.co.uk within 7 days of delivery with the subject “Matching Guarantee Claim – [order number]”. Claims are resolved within 24 hours, with a replacement pair as standard, or a full refund on request.

Clip each head as its own sphere, and treat the space between heads as part of the shape — on a multi-stem plant, the gaps are the form. Left to merge, three spheres collapse into one mass and the stems lose their point. Work round each ball separately, keep a clear gap where two heads face each other, and clip in late May and again in early August; after mid-August, put the shears away. The open centre is doing a job too: it lets light and air reach the low head, and on conifers, foliage left in shade inside the plant turns brown. There's a full walkthrough of when and how to trim a ball-shaped plant in the journal.

Yes, as soon as they appear. The bare stems are half the look, and a shoot left to grow on one thickens into a branch that blurs the line between stem and head. Rub young shoots off with your thumb while they're still soft, or snip them flush with secateurs once they've firmed up, and run your eye down all three stems whenever you water through the growing season. The same goes for anything rising from the base: if it isn't one of the three stems or part of a head, it comes off.

It depends on the species and the size you choose, and it varies from stem to stem on the same plant. As a guide, Delavay privet and Gold Rider carry balls of roughly 20–40cm across, Pink Marble photinia and Blue Arizona cypress roughly 25–45cm, and the compact Japanese holly roughly 15–30cm. Overall heights are measured from the compost surface to the top ball, not including the pot: 70–90cm for the holly; 110–130cm or 150–170cm for the privet; 130–150cm for Gold Rider; 130–150cm, 150–170cm or 170–200cm for Pink Marble; and 170–200cm for Blue Arizona.

The routine is shared: clip each head in late May and early August, water pots 2–3 times a week through summer — check with a finger and water when the compost is dry at 5cm — and give one slow-release feed in spring. Most species then add one rule of their own. Gold Rider and Blue Arizona are cypresses: never cut back into brown wood, because it won't regrow. Delavay privet regrows fast and forgives a misjudged cut, even from bare wood. Pink Marble photinia throws the odd all-green shoot; cut it out completely, or back into variegated growth, or it will outgrow the marbling. Japanese holly takes the same two clips, late May and early August. For winter, Gold Rider is hardy to about −15 to −20°C, Japanese holly −15 to −18°C, Pink Marble −10 to −15°C and privet −10 to −12°C; Blue Arizona is very cold-tolerant once established, provided its pot drains freely and it is sheltered from cold, drying winds. In northern England and Scotland, wrap every pot every winter; in the Midlands and the south, wrap privet and terracotta pots when below about −8°C is forecast. The winter protection guide has the method.

Your pair's quality-control certificate: a record of the plants' origins and dimensions, with six photographs of the actual two plants allocated to you — so you see the stems, the heads and the match before anything leaves. You then have a 24-hour review window to come back to us with anything; if we hear nothing, dispatch proceeds as planned. Allow 14–21 working days from order, or 21–28 in peak season (February to May). After that comes a dispatch email with an estimated delivery date — we can give you a delivery window on request — and the driver calls about an hour before the pallet arrives; there is no online tracking portal. Once the pair is home, the 6-Month Thrive Guarantee takes over: if one plant fails to thrive, email hello@topiarytwins.co.uk with the subject “Thrive Guarantee Claim – [order number]” and we review eligibility within 48 hours.
