Designer Plants is running a 20% off promo code for orders over $300, which is the main discount offer on the page right now. It is best for shoppers spending above that threshold who want a straightforward, code-based discount on their entire order. However, Designer Plants also has several sale markdowns on specific product categories, and some of these deliver bigger savings on smaller baskets.
On orders under $300: The 20% off code does not apply, so you will save most money by shopping the sales that match what you need. If you are buying artificial green walls, the up to 50% off sale could take your bill down significantly, depending on which products are marked down. Artificial vertical garden panels have an up to 70% off sale, while the major clearance event runs up to 78% off on select items across multiple categories including artificial green walls and vertical gardens. Check which sale includes the items in your cart, then compare the final prices before and after the markdown to find the biggest saving.
On a $300 to $500 order: The 20% off code is worth comparing against the sales. On a $400 order using the code, for example, you would save $80 and pay $320. Against that, if you are buying artificial vertical garden panels and they qualify for the up to 70% off sale, a $400 spend could drop to as low as $120, saving you $280. However, not all products are included in the 70% off offer, so add your items to your cart under both the code and the sale prices to see which comes out ahead on the specific things you want.
On larger orders above $500: The 20% off code starts to compete more strongly with the sales. On a $600 order, the code saves you $120 and costs you $480. The up to 70% off sale on vertical garden panels could beat that if your whole cart qualifies, but most orders will contain items outside the sale categories. The major clearance event with up to 78% off is the biggest potential saving, though again it applies only to select items and availability is limited. Build your cart and compare the final totals: the code applies to your entire order, but the sales apply only to the marked down products within it.
If you use the 10-inch UV zip ties: These are 17% off in a dedicated sale, which is less than the 20% off code threshold or most of the bigger percentage sales. If the zip ties are part of a larger order over $300, applying the 20% off code to the whole basket will save you more than the 17% off the zip ties alone.

According to our records, Designer Plants has offered 20 deals in the 12 months to October 2026. The biggest percentage code in that time was 25% off in February 2026, so the current 20% off is below average for this brand's codes. The biggest sale markdown was the 78% off clearance now running, which matches the highest we have seen from Designer Plants in the past year. Our team tested 8 Designer Plants codes at checkout in the 12 months to October 2026.
To decide between the code and the sales, work out your final price under each option. Use the 20% off code if it saves more on your total basket when it qualifies, or pick the sale that applies to your items and gives the lowest total cost.
